May the best (paper) plane win

Those paper airplanes you made in high school? Turns out they weren’t a total waste of time, especially not if you bring your folding skills to the Air & Space Museum’s Paper Airplane Festival on Saturday.

The popular event celebrates the best in aeronautical paper design. Families will learn how to create a variety of airplane makes and models that will be judged in categories like farthest flight distance, longest air time and flight accuracy.

Stick around for the group launch at 3 p.m.
